Many people are wondering when they buy lights or when they see others using LED grow lights. Why do they use LED grow lights? Here we will help you answer.
First of all, we need to understand LED grow lights.
A growth lamp is an electric light to help plants grow. Grow lights either try to provide a light spectrum that is similar to that of the sun, or to provide a spectrum that is more suitable for the needs of the plants being cultivated. Outdoor conditions are simulated by the different colors, temperature, and spectral output of the growth lamp, and the intensity of the lamp. Depending on the type of plant being cultivated, the stage of cultivation (such as the germination/vegetative period or the flowering/fruiting period) and the photoperiod, specific spectral range, luminous efficiency, and color temperature required by the plant, it is suitable for use with specific plants and time periods. Used in gardening, indoor gardening, plant propagation, and food production, including indoor hydroponics and aquatic plants. Although most plant growth lights are used in industrial grades, they can also be used in homes.
In recent years, LED technology has been introduced into the grow lights market. By using diodes to design indoor growth lights, the light of specific wavelengths can be produced. NASA has tested LED growth lights because of their high efficiency in growing food in space for alien colonization. Research results indicate that plants are affected by light in the red, green, and blue parts of the visible spectrum.
LED grow lights to provide full-spectrum light, aiming to imitate natural light and provide plants with a balanced red, blue and green spectrum. The spectrum used varies, but the white LED grow lights are designed to emit similar amounts of red and blue light and add green light to appear white. White LED grow lights are usually used for supplementary lighting in homes and office spaces.
Historically, LED lighting has been very expensive, but over time, the cost has been greatly reduced, and its longevity has made it more popular. The price of LED grows lights is usually higher than other LED lighting because its design features help improve energy efficiency and service life. Especially due to the relatively high power of LED grow lights, LED grow lights are usually equipped with a cooling system because the low temperature can improve brightness and life. The LED usually lasts 50,000-90,000 hours until it reaches LM-70.
Advantages and disadvantages of LED growth lights
If you understand it, then you know why you should buy LED grow lights. You have a better understanding of regret after reading the following.
LED grow lights are on top of the world. In terms of indoor farming, LED lighting technology has been soaring. If it has not surpassed the traditional lighting system, it will soon surpass. LED lights are the technology of the future. Compared with other types of horticultural lighting, they have many huge advantages. In other words, they also have several disadvantages. But these shortcomings are disappearing quickly because manufacturers are making their lights more efficient and cheaper.
Advantages of LED grow lights
The spectrum is the best proof of whether a lamp is useful for your planting. A good LED grow light will produce a balanced full-spectrum light. They provide you with all the light that plants need. The idea that plants need only red and blue light alone is outdated. In addition, most lamps allow you to turn off specific wavelengths, so you can produce perfect light for each stage of plant growth. This means that LED lights are actually better for your plants than natural light.
LED grow lights allow us to adjust the wavelength of light, which means that we can provide plants with the exact light (action spectrum) needed for photosynthesis.
Traditional lighting systems emit a lot of green and yellow wavelengths of light, and plants do not use these lights. Although they need green light and yellow light, these two kinds of light have little effect on plants. Using LEDs, you can provide plants with the exact spectrum they need. No light will be wasted, you can make full use of your energy.
Energy saving is important for a grower. The more energy you save, the less money you invest and the less you spend. LED grow lights are more efficient than traditional lighting systems and can reduce energy by 60% to provide the same Horizontal light.
Compared with traditional lighting systems, they emit less heat and provide more usable light. This is because LEDs will not burn anything to produce light. Due to reduced energy use and heat production, LED grow lights greatly reduce energy costs.
Extend your life
The lifespan of LED grow lights exceeds 50,000 hours, which is 3-4 times longer than traditional lighting systems. An important reason for this is the low operating temperature of the lamp.
Traditional lighting systems will generate a lot of heat, which significantly shortens their service life, and a lot of heat will affect the growth of plants and may burn them. The longer lifespan of LEDs means that you can grow crops for many years without replacing the lighting system, thereby reducing costs.
Fast harvest cycle
LED grow lights can be used for 24 hours, but growers must not use it 24 hours, after all, plants also need to "sleep". The heat emitted by LED grow lights has little effect on temperature. When growing plants indoors, the lack of environmental feedback means that plants rely on you to tell them what season it is and how they should behave.
The use of LED lights enables you to change the time of day and the amount of light of the red wavelength at the right time to maximize the growth rate of plants.
When LED lights are used to grow automatic flowering plants, there may be multiple harvests in one season. You can change the flowering time of the plant and increase the yield to obtain greater benefits.
LED grow lights are 100% recyclable. Unlike HID lamps, they do not contain toxic substances such as mercury. To ensure this, all high-quality LED grow lights have passed RoHS certification.
Disadvantages of LED grow lights
Despite its many advantages and growing popularity, gardening LED lights do have some disadvantages.
Generate directional light
LED lamps provide directional light like flashlights. They usually cover an area smaller than that covered by traditional lighting systems. However, the latest LED grow lights have solved this problem.
High purchasing cost
LED grow lights are much more expensive than HID or fluorescent lights. At least the good thing is,
You can find some lamps that are actually cheaper than HID lamps, but they are not very good.
In other words, there are now several high-quality LED companies selling their lamps at very low costs. You can even buy very good fixtures for less than $100.
LED grow lights produce bright blue light (among other colors), which can cause blindness in humans. But there are many protective glasses on the market, and the price is very cheap, so there is no need to worry about this problem.
With age, LEDs may also start to change color. Despite their long lifespan, they may not consistently produce the expected light quality as they age. For cheaper LED chips, this is even more of a problem. If you buy a high-quality lamp from a reputable company, you don't have to worry about this problem, because a good LED lamp bead can have a very stable work efficiency.
Advantages and disadvantages of LED lights: final thoughts
LED grow lights are almost certainly the future of the gardening industry. Even today, the advantages outweigh the disadvantages, and higher costs are the only serious disadvantage. As prices fall, this shortcoming is quickly disappearing. Good LED grow lights work well, and they can easily surpass any other type of garden lighting on the market today.
